From your dump it looks like the DirectX DLLs have been unloaded and reloaded a few times since dolphin started. This shouldn't be an issue, but it seems XAudio2 has been reloaded to a different address, which also shouldn't be an issue, but is weird.
Please try this binary and let me know if it changes things: https://dl.dropboxusercontent.com/u/3596749/DolphinWX.7z
The binary doesn't have any actual fixes, it's just using the win8 version of xaudio2 and manually controls loading of the dll. It also ensures dolphin loads at it's expected base address (which the jit currently requires, unfortunately).
